Italy Business Registration Guide 2026 — S.r.l., S.p.A., Forfettario

Overview of Business Structures

Italy offers several legal forms for carrying on business activities, each with different tax and liability implications. The choice depends on the size and nature of the business, the number of founders, liability considerations, and tax planning objectives.

Key Business Forms: (1) Ditta Individuale (sole proprietorship) — simplest form, full personal liability. (2) S.r.l. (Società a Responsabilità Limitata) — limited liability company, most popular for SMEs. (3) S.r.l.s. (S.r.l. Semplificata) — simplified S.r.l. with minimum capital of €1. (4) S.p.A. (Società per Azioni) — joint-stock company for larger enterprises. (5) Società in Nome Collettivo (S.n.c.) — general partnership (unlimited liability). (6) Società in Accomandita Semplice (S.a.s.) — limited partnership. (7) Regime Forfettario — simplified tax regime for sole traders with revenue under €85,000.

Sole Proprietorship (Ditta Individuale) and Partita IVA

A ditta individuale is the simplest form of business. The owner has unlimited personal liability for all business debts. Registration requires obtaining a partita IVA (VAT number) from the Agenzia delle Entrate, registration with INPS (Gestione Artigiani e Commercianti or Gestione Separata), and registration with the Camera di Commercio (Chamber of Commerce) — REA (Repertorio Economico Amministrativo). The process can be done online through the ComUnica portal (single business registration form) and typically takes 1-3 business days.

Tax Treatment: Sole proprietors are subject to: IRPEF at progressive rates on business income (reddito d'impresa), INPS contributions (Gestione Artigiani/Commercianti or Gestione Separata), and IVA (unless opting for the regime forfettario). Business income is calculated as gross revenue minus deductible expenses. The sole proprietor files the annual tax return using Modello Redditi PF (quadro LM for business income).

Regime Forfettario (Flat-Rate Regime)

The regime forfettario is a simplified tax regime available to sole proprietors and self-employed individuals who meet the following conditions: (a) annual revenue or compensation under €85,000, (b) total employee costs under €20,000 per year (excluding occasional collaborators), (c) capital expenditure on tangible assets under €20,000 at the end of the previous year, (d) no purchases of goods for resale exceeding 50% of total revenue, (e) no participation in partnerships, associations, or trusts, and (f) not having been in the ordinary VAT regime in the previous year (unless specific transition rules apply).

Tax Benefits: Instead of progressive IRPEF rates, forfettario taxpayers pay a flat substitute tax of 15% on their taxable income (calculated as gross revenue multiplied by a profitability coefficient specific to the business category — ranging from 40% to 86%). For the first 5 years of activity, a reduced rate of 5% applies (if certain conditions are met). The forfettario regime also means: no IVA is charged on invoices (and no input IVA recovery), no annual VAT return filing, simplified accounting requirements (only invoices and receipts need to be kept, no double-entry bookkeeping), and exemption from IRAP (regional production tax). The 15% (or 5%) substitute tax replaces IRPEF, regional and municipal surcharges.

Limitations: Forfettario taxpayers cannot recover input IVA on their purchases. They cannot deduct expenses to the extent not covered by the coefficient. Cross-border transactions are more complex (the forfettario regime is generally available only to Italian residents with no significant foreign transactions).

S.r.l. (Limited Liability Company)

The S.r.l. (Società a Responsabilità Limitata) is the most common corporate form for SMEs. Key features:

Formation: The company is incorporated by a public notarial deed (atto costitutivo) before an Italian Notaio (notary). The deed must include: company name, registered office (sede legale), share capital (capitale sociale), shareholders (soci), directors (amministratori), and the object of the company (oggetto sociale — the business purpose). The deed is filed with the Registro delle Imprese (Companies Register) at the local Chamber of Commerce within 20 days. The process typically takes 2-4 weeks.

Minimum Capital: The standard S.r.l. requires minimum capital of €10,000 (of which at least 25% must be paid up upon incorporation). The S.r.l.s. (Semplificata) requires minimum capital of €1 and is available to individuals only (not companies), with the articles of association in a standard form. The S.r.l. SEME (with a single shareholder — unipersonale) allows a sole shareholder to incorporate with reduced requirements.

Tax Treatment: The S.r.l. is subject to IRES (24%) on taxable income, IRAP (3.9% standard, varies by region), and IVA (standard 22% with reduced rates for certain goods/services). Distributions of dividends to shareholders are subject to 26% withholding tax (for Italian resident shareholders). The company must file annual financial statements at the Companies Register and file the annual tax return (Modello Redditi SC).

S.p.A. (Joint-Stock Company)

The S.p.A. (Società per Azioni) is suitable for larger enterprises seeking to raise capital from the public or list on the stock exchange. Key features: minimum capital of €50,000 (must be fully paid up on incorporation), shares can be listed on Borsa Italiana (Milan Stock Exchange), more complex governance structure (board of directors, board of statutory auditors, shareholders' meeting), and stricter reporting and audit requirements. The S.p.A. is subject to the same tax rates as the S.r.l. (IRES 24%, IRAP 3.9%). It may also opt for the tax consolidation regime (consolidato fiscale) with subsidiaries.

Foreign Entrepreneurs

Non-EU nationals wishing to start a business in Italy must obtain the appropriate visa: (a) Visto per Lavoro Autonomo (self-employment visa) — requires a positive opinion from the relevant professional order (if regulated) and a business plan demonstrating sufficient financial resources, (b) Startup Visa — for innovative startup founders (accelerated process through a dedicated committee at the Ministry of Economic Development), (c) Investor Visa — for individuals investing at least €500,000 in an innovative startup or €1M in a corporate bond/equity investment (or €2M in government bonds). EU nationals do not need a visa and can register for a partita IVA immediately upon arrival.

Branch of Foreign Company: A non-resident company may operate in Italy through a branch (stabile organizzazione — permanent establishment). The branch must be registered with the Companies Register and obtain a partita IVA. The branch is subject to Italian corporate tax (IRES 24%, IRAP 3.9%) on profits attributable to the Italian permanent establishment. Repatriation of branch profits to the head office is generally subject to a final withholding tax of 26% (reduced under treaties). The branch must file annual financial statements and tax returns in Italy.

FAQs

How long does it take to register a company in Italy?

The timeline depends on the business form. A sole proprietorship (ditta individuale) can be registered in 1-3 business days through the ComUnica portal. An S.r.l. requires engaging a Notaio, drafting the articles of association, and filing with the Companies Register — this typically takes 2-4 weeks. An S.p.A. takes longer due to more complex documentation and governance requirements (4-8 weeks). The cost also varies: a ditta individuale costs approximately €200-€500 (registration fees, professional fees), while an S.r.l. costs approximately €2,000-€4,000 (including notary fees, registration taxes, professional fees), and an S.p.A. costs €5,000+.

Can I register an S.r.l. online?

Partially. The ComUnica portal allows you to register a ditta individuale or apply for a partita IVA entirely online. However, for an S.r.l., the articles of association must be executed as a public deed before a Notaio (notary), which requires a physical meeting (or a video-notarisation in some cases since the post-COVID reforms). Some law firms offer digital services where the notarial deed is signed electronically, but in-person notarisation remains the standard. The subsequent registration with the Companies Register can be done online by the Notaio.

What are the ongoing compliance requirements?

All businesses with a partita IVA have ongoing obligations: (a) E-invoicing — mandatory electronic invoicing (fattura elettronica) through the SdI (Sistema di Interscambio) for all domestic B2B/B2C transactions, (b) VAT returns — periodic (monthly/quarterly) VAT summaries (LIPE) and annual VAT return, (c) Annual tax return — Modello Redditi (PF for individuals, SC for companies) by 30 November, (d) INPS contributions — quarterly or annual payments for self-employed, (e) Financial statements — annual bilancio (balance sheet, income statement, notes) filed at the Companies Register (for S.r.l. and S.p.A.), (f) Nomina del commercialista — you will likely need to engage a commercialista (accountant) to manage these filings, as Italian tax compliance is complex even for straightforward businesses.
